[Detailed Description of the Invention] [Object of the Invention] (Industrial Application Field) The present invention relates to a lock device with an electromagnetic release used in an automatic teller machine (ATM) that handles cash, a cash dispenser (CD), etc. Regarding.

(Prior Art) The external configuration of a commonly used automatic teller machine 50 is shown in FIGS. 11 and 12.

A plurality of such automatic teller machines 50 are usually placed in corners of banks, and the number of keys held by staff members who manage these machines increases accordingly. In other words, the staff must select a key for each vehicle, resulting in poor operability.

For this reason, in recent years, a magnetic card C is used to read the magnetic information of the magnetic card C with a card reading device 51 installed in advance in the automatic teller machine 50 to unlock the electromagnetic lock release device 52. In this way, one magnetic card C can be used in a plurality of automatic teller machines 50.

In FIGS. 11 and 12, 53 is a lock for emergency unlocking when the power is turned off, and 54 is a rear door.

As shown in FIG. 13, in the lock release device 52, when the electromagnetic solenoid 57 is energized, the lock lever 58 is attracted in the direction of the arrow X, and the lock lever 58 is released from the fixed wall 50a of the automatic teller machine 50. , the lock is now unlocked.

Further, as shown in FIG. 14, when a key is inserted into the emergency lock 53 and the key is turned, a lever 60 that is linked to the key drives a pin 58a attached to the lock key 58. The lock lever 58 is released from the locked state.

(Problems to be Solved by the Invention) However, in the case of the conventional lock release device 52 described above, there is a problem that a large capacity electromagnetic solenoid 57 is used and the lock release device 52 itself requires a large amount of space. .

Furthermore, in recent years, as shown in FIG. 11, when the rear door 54 is opened, a banknote unit 61. Coin unit 62, passbook unit 63. A card unit 64 is built in, and each of the units 61 to 64 is also equipped with a banknote storage, a coin storage 9, and a bankbook storage.
62a.

63a etc. are provided.

From the viewpoint of operability, these locks 61a and 62a.

63a as well, an electromagnetic release method similar to that described above is desirable and actually desired.

However, when using the conventional lock release device 52,
It is not possible to reduce the size of each unit 61 to 64,
This results in an increase in the size of the automatic cash deposit/dispensing machine 50 (as well as an increase in power consumption due to the use of a large number of electromagnetic solenoids 57) and a rise in manufacturing costs.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a lock device with an electromagnetic release that can be locked and unlocked by key operation, and that can save space, save power, and reduce costs.

[Structure of the Invention (Means for Solving the Problems) The lock device with electromagnetic release of the present invention includes a device body that is cylindrical and has an engagement opening inside, and a device that is rotatably attached to the device body. a cylinder part with a key insertion slot, a lock pin attached to the cylinder part in a state biased toward the engagement recess, and an electromagnet that applies an electromagnetic force in the direction of disengaging the lock pin when energized. an electromagnetic locking mechanism section including a permanent magnet; and a key including a permanent magnet that is inserted into the key insertion slot and applies a magnetic force in an engagement release direction to the lock pin through interaction with the permanent magnet. It is something that you have.

(Function) According to the lock device with electromagnetic release having the above-described configuration, by energizing the electromagnet in the electromagnetic lock mechanism, the electromagnetic lock mechanism releases the lock pin that is urged toward the engagement recess of the device body. Due to the interaction between the electromagnet and the permanent magnet, an electromagnetic force is applied in the direction of disengaging the lock pin, which causes the lock pin to disengage from the engagement recess and enter the unlocked state.

Furthermore, when a key is inserted into the key insertion slot, a magnetic force in the direction of disengaging is applied to the lock pin due to the interaction between the permanent magnet provided in the key and the permanent magnet in the electromagnetic locking mechanism. The lock pin separates from the engagement recess and becomes unlocked.

(Example) Examples of the present invention will be described in detail below.

The lock device 1 with electromagnetic release shown in FIGS. 1 to 5 includes a substantially cylindrical device main body 2, a cylinder portion 3 fitted with the device main body 2 and equipped with a knob 3a and a key insertion hole 3b, and the device body 2. 4. Nuts for mounting to the housing each attached to the outer periphery of the main body 2. For example, six permanent magnets 8 are arranged in a row in a nut 5 for attaching a lock lever etc., a connector 6 for energizing a built-in coil (described later), and an insertion portion 7a that can be inserted into the key insertion slot 3b as shown in FIG. It has a key 7.

Further, the lock device 1 with electromagnetic release has a cylinder portion 3.
