Description

[Detailed description of the invention] [Purpose of the invention] (Industrial application field) The present invention has mechanically independent processing mechanism units arranged side by side within the device body, and each processing mechanism unit is connected to the device body. This invention relates to an improvement in a unit lock device that can be pulled out.

(Prior Art) A banknote handling device, such as an automatic teller machine, has a dispensing unit and a printer unit housed within the device body, which can be pulled out of the device body as needed.
Many models have been put into practical use because they have the advantage of being extremely easy to manage, such as maintenance and inspection. Normally, this type of apparatus is constructed such that the above-mentioned processing mechanism unit is housed in the upper part of the apparatus main body for ease of operation.

(Problems to be Solved by the Invention) However, there is a serious problem in that when both units are fully pulled out, the center of gravity shifts and, depending on the installation conditions, the device may fall over.

The present invention has been developed based on the above circumstances, and its purpose is to provide a unit lock device configured such that when one processing mechanism unit is pulled out from the device main body, the other processing mechanism unit cannot be pulled out. It is something.

[Structure of the invention] (Means for solving the problems) In order to solve the above problems, the present invention provides mechanically independent processing mechanism units in parallel in the main body of the device, and each processing mechanism In a unit lock device in which the units can be pulled out from the device main body, engaging members are provided on mutually opposing surfaces of the processing mechanism units, and between the movement paths of these engaging members, when one unit is pulled out, the other unit is moved. A pair of levers are provided that engage with the engaging members of the unit, each lever having an engaging piece protruding toward one engaging member and a support piece protruding toward the other engaging member. , the engagement piece is always biased so as to protrude between the movement paths of one of the engagement members and toward the front end surface located in the movement direction of the engagement member, and the support piece is provided between the movement paths of the other engagement member. It is characterized in that the engaging piece is configured to retreat from the movement path of the one engaging member by being pushed back against the urging force by the engaging end surface of the engaging member. be.

(Function) When both of the processing mechanism units arranged in parallel are housed in the main body of the apparatus, the pair of levers are pushed in by the rear end surfaces of the corresponding engagement members, so that the pair of levers closes the engagement pieces. The unit is in a state where it is retracted from the movement path of the engaging member, and both units are in a state where they can be pulled out.

When one unit is pulled out, the engagement member that has pushed the support piece of one lever moves and the engagement piece of that lever protrudes into the movement path of the other engagement member, so that the other unit cannot be pulled out. Even if an attempt is made to pull it out, it cannot be pulled out due to the engagement between the engaging piece of the lever and the other engaging member.

(Example) Hereinafter, an example of the present invention will be described based on the drawings. Reference numeral 1 shown in FIGS. 1 to 3 is the device main body of an automatic teller machine as a banknote handling device, and the front surface of the upper housing 1a of this device main body 1 includes an operation button 2, a card insertion slot 3, and an operation guide. An operation panel 6 equipped with a display section 4, a banknote outlet 5, etc. is attached. Further, in the upper housing 1a having the operation panel 6, there is a dispensing unit 7 as a processing mechanism unit,
A power supply control unit (not shown) is connected to the units 7 and 8 via a flexible cable (not shown).
is accommodated.

Furthermore, the above-mentioned dispensing unit 7 and printer unit 8 can be pulled out rearward by opening and closing the rear doors 9, 9 of the upper housing 1a, as shown by the two-dot chain line in FIGS. 2 and 3. It's summery. That is, as shown in FIG.
Four rails 13 are disposed via the rails 1 and 12, and a dispensing unit mounting base 14 and a printer unit mounting base 15 are slidably mounted via these rails 13. By sliding the dispensing unit mounting base 14 or printer unit mounting base 15 toward the front using the rails 13, 13 as guides, the dispensing unit 7 or printer unit 8 mounted on these mounting bases 14, 15 can be moved. It can be pulled out from the upper housing 1a.

Further, a unit lock device 16 is disposed on the bracket 12 located between the dispensing unit 7 and the printer unit 8, and an engaging member is provided on the dispensing unit mounting base 14 and the printer unit mounting base 15. Lock fittings 17 and 18 are attached, and when either unit 7 or 8 is pulled out, the other unit 8
Alternatively, the configuration is such that 7 cannot be drawn out. That is, as shown in FIG. 5, first and second locking levers 22 and 23 are rotated by a support shaft 21 on a support plate 20 that is mounted on a bracket 12 via set screws 19 and 19. It is pivoted for free movement. These locking levers 22, 23 are formed into a crank shape and have hook portions 24, 24 on the free end side, and the vertical pieces 17a, 18 of the lock fittings 17, 18
an engagement piece portion 22a that can be engaged with and disengaged from the front edge of a;
23a is formed, and a support having pressing force receiving surfaces 25, 25 and spring locking portions 26, 26 that come into contact with the rear end surfaces of the vertical pieces 18a, 17a of the lock fittings 18, 17 on the shaft support end side. Piece 22
b, 23b are formed.

Further, each of the spring locking pieces 26, 26 of the first and second locking levers 22, 23 has one end connected to a spring locking piece 26 formed on the support plate 20.
The other ends of the springs 28 and 28 that are locked to 7 and 27 are locked, so that the first locking lever 22 always rotates counterclockwise, and the second locking lever 23 always rotates clockwise. energized.

Therefore, when the dispensing unit 7 and the printer unit 8 are housed in the upper housing 1a, the lock fittings 17 and 18 are in the positions shown by the solid line and the two-dot chain line in FIG. Pressing force receiving surfaces 2 formed on the support pieces 22b, 23b of the first and second locking levers 22, 23 by the rear end surfaces of the vertical pieces 17a, 18a of the metal fittings 17, 18
5 and 25 are pushed in against the urging force of springs 28 and 28. Therefore, the first and second
The locking levers 22 and 23 are in the state shown by the two-dot chain line and the solid line in FIG.
Both units 7 and 8 are in a state where they can be pulled out.

Next, when the printer unit 8 is pulled out, the locking metal fitting 18, which was holding down the pressing force receiving surface 25 of the support piece 22b of the first locking lever 22 against the biasing force of the spring 28, moves in the direction of arrow A. In order to move, the first locking lever 22 is rotated counterclockwise about the support shaft 21 and enters the state shown by the solid line.
Then, the engaging piece 22a is projected into the movement path of the lock fitting 17 that is integrated with the dispensing unit mounting base 14, and even if an attempt is made to pull out the dispensing unit 7, the hook section 24 of the first locking lever 22 will be blocked. engaging piece 22
a and the front edge of the vertical piece 17a of the lock fitting 17 engage with each other to lock the dispensing unit 7.

Moreover, if the dispensing unit 7 is taken out first, the engaging piece 2 of the second locking lever 23 will be moved in the same manner as described above.
3a engages with a lock fitting 18 integrated with the printer unit mounting base 15 to lock the printer unit 8.

Therefore, when one unit 7 or 8 is pulled out, the other unit 8 or 7 is locked and cannot be pulled out. This prevents the center of gravity from shifting significantly due to pulling out both units completely, and prevents the equipment from falling over. This will definitely be prevented.

[Effects of the invention] As explained above, although the present invention has a simple configuration, when one processing mechanism unit is pulled out from the main body of the apparatus, the other processing mechanism unit is locked and cannot be pulled out. It is possible to reliably prevent the device from falling over due to a large shift in the center of gravity due to pulling out the entire unit. Furthermore, since it is not necessary to provide the device over the entire length of the processing mechanism unit in the direction in which it is pulled out, the device itself can be made smaller.
