Abstract

PURPOSE:To confirm the connection state of a mechanical connector and to secure the confirmed connection of the connector by forming a pierced hole led to a circuit substrate on a mechanism chassis at a point near the connector. CONSTITUTION:A connector 3 of a rotary head 2 attached to a mechanism chassis 1 is connected to a connector 5 provided on a circuit substrate 4. The connection state between both the connectors 3 and 5 can be confirmed through a pierced hole 7. If the connectors 3 and 5 are incompletely inserted, these connectors are pushed again and surely connected together. Thus the confirmed connection is guaranteed between both connectors 3 and 5. Then the reliability is improved for a magnetic recording/reproducing device.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a magnetic recording / reproducing apparatus such as a VTR, DAT, tape recorder and the like.

[0002]

2. Description of the Related Art In recent years, a magnetic recording / reproducing apparatus has a complicated mechanism function, and many electric parts such as a motor / head, a switch for detecting a cassette, a position detecting element for controlling a mechanism, etc. are mounted on the mechanism. became. Therefore, a connector is generally used for signal transmission between the mechanism and the control circuit. Furthermore, there is a structure in which the connector is connected to the circuit side at the same time as the mechanism is attached to the frame of the deck in response to the recent reduction in size and weight.

An example of the above-mentioned conventional magnetic recording / reproducing apparatus will be described below with reference to the drawings. FIG. 5 shows a state in which a mechanism in which a rotary head is attached around a rotary head portion of a conventional magnetic recording / reproducing apparatus is connected to a circuit board via a connector.

The rotary head 5 is attached to the mechanism chassis 51.
2 is attached to the rotary head 52, and a mechanical connector 53 for transmitting signals from the head is attached to the rotary head 52 to connect with a board connector 55 provided on a circuit board 54. The mechanism chassis 51 is connected to the frame 56 to connect the connectors.
It is done by being attached to.

[0005]

However, in the above structure, when the mechanism chassis is attached to the frame, it is not possible to confirm whether the connectors are securely connected or not. Moreover, even if it is found that the stroke of the connector is insufficient, there is a problem that it cannot be pushed in later.

In view of the above problems, the present invention can confirm the connection state after the mechanism chassis is attached to the frame and the connector is connected, and at the same time, if the connection is incomplete, the connector can be pushed in again. The present invention provides a high-performance magnetic recording / reproducing apparatus.

[0007]

In order to solve the above-mentioned problems, a magnetic recording / reproducing apparatus of the present invention has a mechanism chassis, a circuit board, and a frame to which the mechanism chassis and the circuit board are attached, respectively. A pair of connectors that are respectively coupled to each other when the substrate is attached to the frame, that is, a mechanical connector provided on the mechanism chassis and a substrate connector provided on the circuit substrate facing the mechanical connector and coupling; A through hole communicating with the circuit board near the mechanical connector is provided on the mechanism chassis.

[0008]

According to the present invention, with the above-described structure, the connection state can be confirmed after the mechanism chassis is attached to the frame and the connector is connected, and at the same time, if the connection is incomplete, the connector can be pushed in again, which is reliable. It is intended to provide a highly reliable magnetic recording / reproducing apparatus which can be connected.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A magnetic recording / reproducing apparatus according to an embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows a state in which a mechanism in which a rotary head is mounted around a rotary head portion of a magnetic recording / reproducing apparatus according to a first embodiment of the present invention is connected to a circuit board via a connector. A rotary head 2 is attached to the mechanism chassis 1, and a mechanical connector 3 for transmitting signals from the head is attached to the rotary head 2 and is connected to a board connector 5 provided on a circuit board 4. When the mechanism chassis 1 is also attached to the frame 6, the pair of connectors facing each other are connected to the circuit board 4 attached in advance to the frame 6. The mechanism chassis 1 has a through hole 7 just above the connector connecting portion.
Is provided.

Details of the structure of the connector connecting portion are shown in FIGS.
Will be explained. FIG. 2 is a perspective view of FIG. The state of the through hole 7 is shown in FIG. The connector connection is visible through the through hole 7. Further details will be described with reference to FIGS. 3 and 4. FIG. 3 is an enlarged view of the connector connecting portion from the side, and FIG. 4 is an exploded view of parts around the connector. Although the mechanical connector 3 and the board connector 5 are in a connected state in FIG. 3, the mechanical connector 3 is soldered to the printed board 8. The printed circuit board 8 is attached to the holding member 11 together with the guide member 9 with stepped screws 10. The holding member 11 is attached to the fixed portion of the rotary head 2. Although not shown, a signal from the rotary head 2 is transmitted to the printed board 8 by a lead wire. At this time, since the printed circuit board 8 is mounted with a clearance A in the plate pressure direction and a clearance B in the radial direction of the stepped screw 10, a slight movable range exists in any of the up, down, front, back, left, and right directions. To do. This movable range absorbs the vertical, front-rear, left-right positional deviations of the mechanism chassis 1 and the circuit board 4.

In FIG. 4, the pin 9a provided on the guide member 9 engages with the hole 8b provided on the printed circuit board 8. The printed circuit board 8 and the guide member 9 are substantially integrally coupled. Since the printed board 8 is attached with a slight movable range, the guide hole 9b of the guide member 9 and the guide shaft 12 provided on the circuit board 4 guide the connector connection until the connector is connected. Done.

In the magnetic recording / reproducing apparatus having the above-mentioned structure, the mechanical connector 3 and the substrate connector 5 are connected to each other, and the movable range in the vertical direction causes a shortage of the connecting stroke. By pressing the mechanical connector 3 from the through hole 7 through the guide member 9 with a simple tool such as a screwdriver, a reliable connection can be achieved. Further, when the connector is connected incompletely, the insertion load of the connector is applied to the mechanism chassis 1 via the rotary head 2 and the mechanism chassis 1 is distorted. The present invention provides an excellent magnetic recording / reproducing apparatus which can solve such problems extremely easily by pushing the connector after the above.

Although the connector is pushed through the guide member 9 on the upper side of the mechanical connector 3 in this embodiment, the mechanical connector may be pushed directly.

[0014]

As described above, according to the present invention, there are the mechanism chassis and the circuit board, and the frames to which the mechanism chassis and the circuit board are attached, respectively, and the mechanism chassis and the circuit board are connected to each other in the state of being attached to the frame. A pair of connectors, that is, a mechanical connector provided on the mechanism chassis and a board connector provided on the circuit board facing and coupled with the mechanical connector, and a through hole communicating with the circuit board in the vicinity of the mechanical connector. Since the holes are provided on the mechanism chassis, the connection status can be confirmed after the mechanism chassis is attached to the frame and the connector is connected, and at the same time, if the connection is incomplete, push the connector again. Reliable magnetism that enables reliable connection There is provided a recording and reproducing apparatus.
