Abstract

PURPOSE:To markedly improve unit attachment/detachment work with no need of work to avoid interference by avoiding interference due to rotation of other units in the work of extracting one unit. CONSTITUTION:A unit is exemplified by a display 2 and a printer 3. First, retraction of the display 2 and the printer 3 is as follows: the printer 3 is pushed deep into a case 1 of the printer 3 with the rear end of the display 2 down. Next, extraction of the truck 10 pushes the rear end of the display 2 upward by moving the truck 10. Rotation of the display 2 causes a following plate 13 to be displaced in a horizontal direction. A horizontal state of the display 2 is maintained, and the printer 3 is extracted up to a maintainable state. In the case of retracting the printer 3, pushing the truck in brings retraction as original. This process enables extraction and retraction of units by one action and prevents units from being damaged by interference of units.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a unit attaching / detaching device for facilitating attachment / detachment of the unit in various kinds of equipment such as office automation equipment composed of a plurality of units.

[0002]

2. Description of the Related Art OA equipment and the like are equipped with a display device such as a CRT in order to display various information such as the state of work, and are often tilted according to the line of sight of an operator.
In such an OA device, since the unit housed inside the device, for example, the printer is maintained and inspected, the inclined display device interferes when the printer is pulled out to the front. Therefore, the conventional unit attaching / detaching device has a mechanism for temporarily maintaining the display device horizontally by hand.

A conventional unit attaching / detaching device will be described with reference to FIGS.

Reference numeral 1 denotes a casing, a display device 2 is provided on the casing 1, and a printer 3 is provided below the display device 2.
Is provided.

The display device 2 includes a display body 4 and a case 5
The case 5 is rotatably supported below the front end. A roller 6 is provided at the lower rear end of the case 5 and is slidably fitted in a groove plate 7 provided on the housing 1 side. A rotary handle 8 is provided above the front surface of the housing 1.

The printer 3 is installed on a carriage 10 that rides on a rail 9 provided on the housing 1.
The printer 3 can be pulled out to the entire surface by pulling out the printer 3 to the entire surface.

[0007]

When the maintenance of the printer 3 is attempted by the above-mentioned conventional unit attaching / detaching device, first the display device 2 is rotated by the rotary handle 8 until it becomes horizontal, and then fixed not shown. Fix it horizontally with the device,
Next, the printer 3 was pulled out.

Therefore, in order to bring the printer 3 into a maintainable state, there are two behaviors, that is, an operation of rotating the display device 2 to a horizontal state and an operation of pulling out the printer 3, and the workability is poor. Furthermore, if the printer 3 is pulled out without forgetting the rotation operation of the display device 2, the printer 3 and the display device 2 may buffer each other, resulting in an accident of damaging the display device 2 and the printer 3.

In view of the above situation, the present invention is designed so that the units can be moved in and out with one movement and the units are not damaged by the interference between the units.

[0010]

According to the present invention, one unit is provided so as to be swingable, and another unit is provided below the one unit so as to be horizontally movable. Connect one unit to the other
It is characterized in that the one unit is configured to swing by horizontal movement of the one unit.

[0011]

With the swinging of one unit due to the horizontal movement of the other unit, the interference between the other unit and the one unit is avoided, and therefore the horizontal movement of the other unit is performed without any hindrance. Also, the attachment and detachment of the unit may be one action of the drawer of the other unit.

[0012]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

1 and 2, the same parts as those shown in FIGS. 4 and 5 are designated by the same reference numerals.

A cam plate 11 is provided along the side edge of the carriage 10.
To provide. A cam groove 12 is formed near the front end of the cam plate 11 so as to be inclined toward the rear end from the upper surface. Display device 2
A driven plate 13 is provided below the rear end so as to face the cam groove 12 at a position where the carriage 10 is pushed. The driven plate 13 is provided with a long hole 14 extending in the front-rear direction along the lower edge of the display device 2.

A vertically extending rod 15 is provided below the driven plate 13 so as to be vertically slidable, rollers 16 and 17 are provided at both upper and lower ends of the rod 15, and the upper roller 16 is attached to the driven plate 13. The roller 17 at the lower end is rotatably brought into contact with the upper end surface of the cam plate 11 and can be fitted into the cam groove 12.

The operation will be described below.

First, the display device 2 and the printer 3 are stored in a state where the printer 3 is pushed into the back of the housing 1 and the rear end of the display device 2 is lowered. In such a state, the roller 17 at the lower end of the rod 15 is lowered to the bottom position of the cam groove 12, and thus the rod 15 is lowered to the bottom dead center position.

Next, when the carriage 10 is pulled out for the maintenance work of the printer 3, the movement of the carriage 10 causes the cam groove 12 to push up the roller 17. The movement of the roller 17 is transmitted to the roller 16 via the rod 15 and pushes the rear end of the display device 2 upward. The rotation of the display device 2 causes horizontal displacement of the driven plate 13, and the roller 16 slides along the elongated hole 14.

When the roller 17 disengages from the cam groove 12, the roller 17 rides on the horizontal upper end surface of the cam plate 11 and the vertical displacement is eliminated regardless of the movement of the carriage 10. Thus, the horizontal state of the display device 2 is maintained, and the printer 3 is pulled out to a maintainable state.

When the printer 3 is to be stored, the carriage 1 is used.
If 0 is pushed in, it will be stored by the reverse operation of the case of pulling out.

Further, as another embodiment, the lower required position of the display device 2 and the required position of the carriage 10 may be connected by an inclined link rod 18.

Also in this embodiment, when the carriage 10 is pulled out, the link rod 18 is changed to the upright state and the rear end of the display device 2 is pushed up to be in the horizontal state.

In the other embodiment, if the link rod 18 is slightly tilted in the opposite direction when the carriage 10 is completely pulled out, the display device 2 is in a horizontal state. Maintenance is stable.

Although the display unit and the printer are exemplified as the unit in the above embodiment, it goes without saying that the unit can be implemented as a unit attaching / detaching unit for various units.

[0025]

As described above, according to the present invention, when one unit is pulled out, the other unit is rotated to avoid interference, so that work for avoiding interference is not required, and unit attachment / detachment work is not required. Is greatly improved, and it is possible to prevent damage to the device due to forgetting the work to avoid interference, which is an excellent effect.
