On the front side of the hand grip side portion 104 of the holder 101 there is a first set 108 of manoeuvre buttons 109 for manoeuvring, preferably with the thumb of the right hand. In the example shown there are four buttons 109 or sensors for manoeuvring of the functions up, down, right and left. On the rear side of the hand grip side portion 104 of the holder 101 there is a second set 110 of manoeuvre buttons 111 adapted for the other fingers of the right hand with preferably up to four buttons 111 or touch sensors. Each button 111 in the second set 110 of manoeuvre buttons can, as shown in the drawings, be arranged in a recess 112 for more secure access to the buttons 111.

(18) FIG. 9 shows how a holder 101 with a tablet computer 102 inserted can be arranged on an arm inside a vehicle, preferably a towing vehicle such as a tractor, whereby the holder and computer tablet are used to control certain functions of a towed machine, such as a towed agriculture implement, like a seed drill or the like.

(19) Icons and areas 115a on the screen 115 of the tablet computer 102 refer to functions of the machine. The graphical interface of the tablet computer 102 can be provided with icons or areas 115a that match the buttons 109, 111 and are adapted to alter character, for example light up, when a button 109, 111 is activated. One of the buttons 109, 111 or additional a not shown button can be adapted to activate the tablet computer 102 so that it can be operated through the holder, i.e. a so-called dead man's grip. The buttons 109, 111 can be activated in two steps, i.e. first a function is selected, such as a button 111 on the underside of the holder 101, and then a function is manoeuvred, such as left, right, up, down etc. with a button 109 on the upper side of the holder, or the other way round.

(20) One of the buttons 111 on the underside can activate an icon 115a, which can be pushed upwards/downwards or alternatively to the right/left, whereby one icon 115a on the screen 115 can be used and other icons 115a remain inactive, wherein the icons 115a on the screen 115 of the tablet computer 102 can replace the buttons 109 on the front side, i.e. the buttons 109 activated with the thumb. Furthermore, the buttons 109, 111 and their electronics can be built into the holder 101. The buttons 109, 111 on the holder 101 can alternatively be adapted to communicate wirelessly with the tablet computer 102. The holder 101 can be provided with a socket 116 for a charging cable 113 for the tablet computer 102 and/or the holder 101, wherein when the charging cable 113 is removed only certain functions in the holder 101 are possible to activate. This could be a way to limit the functions when the driver takes the tablet computer 102 outside the cab of the vehicle. Only certain functions of the tablet computer 102 can be allowed/be activated, i.e. certain functions can be blocked when the charging cable 113 is removed from the tablet computer 102.

(21) As shown in FIGS. 5-9 the holder 101 according to the invention of the second embodiment differs from the holder 1 of the first embodiment in that the hand grip side 104 with the key set portion is detachable and can be mounted either on the short side of the holder 101 or on the long side thereof. The reference number 120 denotes snap buttons which are entered in holes 121 to lock the hand grip side portion 104 to the rest of the holder 101. The release of the hand grip side portion 104 from the holder 101 can be such that it is simply drawn out of the snap engagement consisting of the buttons 120 and the holes 121, see especially FIG. 6. In FIG. 5 the tablet computer 102 is placed in the holder 101 with its charging cable 113 in contact on the input side of the holder 101. The charging cable 113 is connected to the tablet computer 102 on the input side of the holder 101.

(22) In FIG. 7 the tablet computer 102 is introduced into by pushing it according to an arrow 119 into the holder from one side of the holder 101. The charging cable contact 122 is on the opposite side compared with the application of FIG. 5 where the tablet computer is snapped into the socket 3a of the frame 3. A charging cable contact 122 of the tablet computer 102 is to be connected to a contact 123 on the holder 101. The contact 123 will then be connected to the contact 124 on the hand grip side portion 104. A contact similar to the contact 123 will be mounted at the long side of the holder 101 for energy supply to the key set portion 101a when it is detachably mounted on the long side of the holder 101 for use when the user intends to engage hand grip side portion 104 on the long side of the holder 101. The positioning of hand grip side portion 104 on the long side or the short side of the holder 101 depends on the space need inside the tractor cabin or on the user's desire. Apart from how the tablet computer 102 is oriented in the holder 101, it is important that the positioning of the buttons 109, 111 on the hand grip side portion 104 is comfortable and ergonomic. Hence, it can be significance that the computer tablet can be turned to different oriented positions.

(23) If the electric supply is broken to the holder 1, 101 the holder can still function the other way with the remaining energy supplied from the computer tablet 2, 102.

(24) Accordingly, the buttons of the hand grip side 4 and the hand grip side portion 104 can operate functions in the computer tablets 2 and 102, respectively, and vice versa. If the low voltage-current to the holder 2, 102 is broken, the in-built battery is able to support the electronic circuits of the hand grip side 4 and the hand grip side portion 104. This can be desirable when the user will use the holder 1, 101 with mounted computer tablet 2, 102 separated from a normal operation position with voltage-current supply in order to wireless operate and test a machine function or any other issue which must be performed without voltage-current supply directly from the machine.

(25) The holder 1, 101 does not necessarily consist of a frame, but can also consist of a frame of gripping arms holding the tablet computer 2, 102 firmly in a known way. This frame could comprise at least one socket on its long side or short side for connecting a handgrip portion which is either firmly or detachably attached thereto.

(26) The holder 1 and 101 according to the invention for a tablet computer 2 and 102 or similar, respectively, can within the framework of the claims be modified as regards combinations of the design details that are described above.
