Description

[Detailed description of the invention] (a) Industrial application field The present invention relates to a unit attachment/detachment device that is ideal for portable electronic equipment, especially when the keyboard of a personal computer, word processor, etc. is not in use or is being transported. This invention relates to a unit attachment/detachment device that is integrated into a main body and has a compact structure.

(b) Conventional technology Generally, office automation (O.A.) such as personal computers and word processors
2. Description of the Related Art In electronic devices used in devices, keyboards are either fixed to the main body or connected to each other by cables, and the keyboard is provided separately.

In recent years, office equipment has become smaller and more sophisticated, and in particular, when making it into a portable type, for example, a personal computer, i.e. the main part including a floppy disk driver (FDD) and CRT display, and a keyboard are combined. Instead, a structure in which the keyboard is integrated with the CRT display while not in use or when being transported has begun to be used. An example of this is Utility Model Application No. 135930/1983 (Application No. 21210/1983) filed by the same applicant.

(c) Problems to be solved by the invention The above-mentioned conventional example requires an operation part and a moving lever on the keyboard side, and the locking piece connected to these is locked on the cabinet body side, so the structure is It was complicated and had the disadvantage of having a large number of parts. The present invention proposes a new configuration that eliminates the above-mentioned drawbacks.

(d) Means for solving the problem The present invention comprises a first unit having a recess, a pressing part inserted into the recess of the first unit, a support leg provided continuously to the pressing part, and a first unit having a recess. a first elastic part continuous to the support leg; a second elastic part continuous to the pressing part and fixed to the first unit;
A locking piece made of synthetic resin having an elastic part and a claw piece provided at one end of the first elastic part, and a second unit having an engagement hole in which the claw piece of the locking piece engages. The second elastic part of the locking piece is fixed to the first unit, and the second unit is detachably attached to the first unit by the locking piece.

(E) Function In the unit attachment/detachment device for electronic equipment of the present invention, when the second unit is attached to or detached from the first unit, the locking piece is fixed to the first unit,
By simply providing a locking hole in the second unit, the second unit can be easily attached and detached by utilizing the elasticity of the locking piece.

(F) Embodiments The present invention will be explained with reference to the drawings. Fig. 1 is a perspective view of a locking piece used in the unit attaching/detaching device for electronic equipment of the present invention, Fig. 2 is a perspective view of the main part of the device, and Fig. 3
The figure shows a cross-sectional view of the main parts of the device, FIG. 4 is a perspective view of the entire device, and FIG. 5 is a side view of the device. part 4, a second elastic part 5, a locking piece having a claw piece 6, 7
has a mounting leg piece 8, a recess 9, and a side wall 10.
The cabinet body 11 as a unit has a locking hole 12, and a second cabinet body 11 is provided with various keys 13.
The keyboard is a unit, 14 is a handle used during transportation, and 15 is a fixing screw.

Next, how to install the device of the present invention will be explained below.The pressing part 2 of the locking piece 1 is inserted from the inside of the cabinet body 7 into the recess 9 provided in the cabinet body 7, and the The second elastic portion 5 of the locking piece 1 is fixed to the leg piece 8 with a screw 15.

In this state, as shown in FIGS. 2, 3A, and 4, the pressing portion 2 of the locking piece 1 is located on the same plane as the side surface of the cabinet body 7.

When the keyboard 11 is left unused or transported in this state, when the keyboard 11 is integrated into the cabinet main body 7, the locking holes 9 of the keyboard 11 are inserted into the fifth tabs 6 of the locking pieces 1.
When the bottom surface of the keyboard 11 is pressed in the direction of arrow A while facing each other as shown in FIG. The claw piece 6 bends inward against the elasticity of the second elastic part 5 and the first elastic part 4, and when the claw piece 6 is completely engaged with the locking hole 9, The claw pieces 6 return to the state shown in FIG. 3A, and are fully engaged, so that the keyboard 11 covers the front of the cabinet body 7 (the display side of a CRT display, etc.) as shown in FIG. 5A. It becomes the composition.

On the other hand, the keyboard 11 is connected to the cabinet body 7.
When removing the locking piece 1 from the second elastic part 5, press the pressing part 2 of the locking piece 1 to the left as shown in FIG.
When the claw piece 6 is moved together with the pressing part 2 toward the inside of the cabinet body 7 against the elasticity of the first part, and the pressing part 2 is further pressed as shown in FIG.
The elastic part 4 hits the base of the mounting leg piece 8 and bends around the base, and the claw piece 6 comes out of the locking hole 9 and crosses the peripheral edge part 16 of the keyboard 11, as shown in FIG. 5B. The keyboard 11 can be removed from the cabinet body 7 by moving the keyboard 11 away from the front surface of the CRT display of the cabinet body 7 as shown.

As explained above, the locking piece 1 is used when the keyboard 11 as the second unit is attached to and removed from the cabinet body 7 as the first unit.
When pressing the pressing portion 2 with a finger to move the claw piece 6 inward of the cabinet body 7, a sufficient stroke or moving distance can be obtained, making the removal operation easier.

(g) Effects of the invention According to the unit attachment/detachment device for electronic equipment of the invention, a locking piece is attached to the cabinet body as the first unit, and the locking piece is provided with two elastic parts. Due to the elasticity of the keyboard, the claws can move a sufficient distance with respect to the locking holes provided in the keyboard as the second unit, making it easy to attach and detach the keyboard to and from the cabinet, and furthermore prevent external forces from being applied. When a force is applied, it is possible to divide the force into two, and even if a strong force is applied to the locking piece, the possibility of breakage can be greatly reduced.
