The present invention forms, for example, a recording table by magnetic tape bonding on a part of a rectangular card, and uses a magnetic card displaying letters and figures on the remaining margins to record and reproduce. The present invention relates to an improvement of a card type recorder in which a magnetic head corresponding to a large track is mechanically switched. The main purpose of the present invention is to stably and accurately position a magnetic head that is predetermined to be switched in this type of recorder. In order to avoid misalignment of tracks during recording and recording and playback, it is also prayed for reasonable improvement of the main part of the recorder.

Hereinafter, specific embodiments of the present invention will be described with reference to the accompanying drawings. 1 is a plan view showing one example of a magnetic card applicable to the original recorder. This is provided with a writing table 2 (in this example, a 6.25 mm width magnetic tape adhesive) of a certain width parallel to the lower side on the surface of the rectangular magnetic card 1 formed of relatively strong lipids and having a margin above it. The part is formed by printing, for example, a foreign language (3) (3a, 3b) to be learned and its translated language (4) (4a, 4b), and the like. Usually, the first track 2a of the writing table 2 is printed. The standard voice of the foreign language 3 is recorded in advance by the instructor, and the student plays the audiovisual and bilateral learning while playing this, and records the student's own pronunciation using the second track 2b. It can be played back and contrasted with standard voice.

That is, the card-holder 2 of the illustrated card has two tracks, and the magnetic heads (erase head, recording head, and playback head) provided with the recorder described below also correspond to each track as described above. It is a 2-track mono system with a switching mechanism. Only such a card recorder and magnetic card 1 as illustrated, it is already known.

2 is an outer perspective view showing an example of a card type recorder embodying the present invention. In the drawing (5), the entire card recorder (6) is a spherical outline formed by joining a shell-shaped upper body 6A and a lower body 6B (any resin molded article) by, for example, a rim. The case (7) indicates a groove for card transfer formed along its longitudinal direction at a position near the right side of the upper body 6A, and the front opening of the groove 7, i.e., near the front of the case 6 The portion is a wide insertion portion 7a for facilitating insertion of the magnetic card 1 (virtual line shown), and both sides between the insertion portion 7a and a certain position of the groove 7 are reached. The side 7b is provided in the edge part.

In the middle of the groove (7), a slightly wider end (8a) on the left side of the large projection (8b) protrudes to the same height, the magnetic card (1) on the surface of the large end (8a) An arrow mark 9 indicating the conveying direction of the arrowhead and the indicator protrusion 10 corresponding to the position of the recording and reproducing head inside the body are formed by the integral molding. In the present example, the groove member including the large end 8a, the protrusion 8b, and the like is a separate molded article, and the member is made of a resin of a different color from the upper body 6A. Reference numeral 11 denotes an operation portion formed as a short cross section at a position near the front left part of the upper body, and on this operation portion 11, the volume knob 12, the student push button 13, and the push button 14 for instructors from the sequential front side. And a recording push button 15, wherein among these operators, the push buttons 13 and 14 are interlocked, for example, through a seesaw link or the like, and when the one is pressed, the other protrudes. It is supposed to be restored. That is, by this operation, each of the first and second tracks 2a and 2b (see Fig. 1) constituting the above-described recording table 2 is associated with the erasing head, recording, and playback head described later. will be.

In addition, the push button 15 shall be locked by the push mechanism, for example in the pushing position only when the push button 14 is pressed. In the card-type recorder 5 of the present example, the left side of the case on which the operation unit 11 is installed is the operation front surface, and the speaker grill 17 is located near the volume knob 12, and the case faces the grill. The speaker 18 is provided in the inside.

By the way, the card type recorder 5 of this example has a surface of the card inserting portion 7a described above, that is, the front of the case. The drawer-shaped handle 19 of the shape is provided for the convenience of carrying the recorder, and in the storage thereof, the handle 19 can be pressed and stored in the case 6 as an arrow. Although the handle itself is widely adopted in a general tape recorder or the like, in this example, the handle 19 as shown is not merely a portable recorder, but is inserted into the transfer groove 7 of the magnetic card 1. In the early days, it was studied to be used as a side guide up to a certain transfer point. In other words, the chassis in the case 5 is provided with an upward C-shaped card guide guide groove as described below, and the lower edge of the card 1 is regulated by the deep end of the groove of the guide. This is made to drive and a magnetic head is made to serve either the 1st track or the 2nd track 2a, 2b. Thus, for example, when the magnetic card 1 is inclined toward the front side of the case by its own weight at the beginning of card transfer, the leading part of the lower side floats in the groove of the guide groove. This can cause malfunctions in the recording and playback functions. Therefore, the present embodiment is considered to allow the upper end surface 19 'of the handle 19 to follow the deep section of the groove of the guide groove installed in the case, thereby eliminating the irrationality as described above.

However, the aspect of the handle 19 is not necessarily limited to the drawer-like structure as illustrated, and it is easily considered to use the known folding folding handle or the like. A part of the upper end surface 19 'of the handle 19, i.e., the card contact portion may be set at a predetermined height position, and in some cases, the sides of the side are guided to the portion holding the lower side of the card. The formations of the handle 19 can also be variously modified as long as they do not prevent the arrangement or formation of the sub-drifts.

3 is a plan view schematically showing the main part of the internal mechanism. In the drawing, reference numeral 20 denotes a chassis installed in the case, and the chassis 20 is formed of, for example, a resin molded article, and a part of the surface thereof has the above-described card transfer groove 7 ( A guide jaw 21 corresponding to FIG. 2 is formed. This guide jaw 21 has a cross-sectional shape, as shown in FIG. 4, and an upward c-shaped groove 22 for guiding the vicinity of both sides of the lower side of the magnetic card 1 illustrated in FIG. The right-hand part forms a wide part 22a almost facing the card insertion part 7a of the groove 7, and a part near the rear part has a capstan and pinch-la, which will be described later. Cutouts 9 (22b) are formed for positioning. 23 denotes the entirety of the head substrate which is disposed substantially parallel to the guide jaw 21 and which can be moved up and down at a predetermined pitch in a direction perpendicular to the ground, and part of the head substrate 23 The elimination head 25 and the recording and reproducing head 26 are fitted around the support shaft 24 upright to the sash 20 and elastically knitted in the clockwise direction. A track of the recording stand 2 of the magnetic card 1 which is driven, which has its heads resting on the guide jaw 21 and is guided by the groove 22 of the guide jaw 21. The second tracks 2a and 2b (see Fig. 1) are in contact with each other.

Numeral 27 denotes a pressing elastic furnace for rotating material disposed as corresponding to the head surface of the erasing head 25, numeral 28 is a cap stand installed against the cutout portion 22b described above, and 28 ' Denotes a flywheel located below the chassis 20 and the flywheel 28 'directly connected to the capstan 28 is driven by a motor, not shown, as in a general tape recorder. However, the capstan 28 of this example is made of a rubber roller which also serves as a card presser and an action in addition to the card transfer. In addition, (29) is a pinch-line pin disposed under the recording and playback head (26), (30) is a bell-crank pinch lever (31) and (32) is a pinch lever- (30) and head Each of the springs for knitting the substrate 23 in a predetermined direction is indicated.

As described above, the card type recorder of the present embodiment mechanically switches the upper and lower positions of the erasing head 25 and the recording and reproducing head 26, but this track switching is performed when the track switch is connected to the head substrate 23. By sore-bar-33. The illustrated seesaw lever 33 is a molded article made of synthetic resin and extends to the above-mentioned operation front side substantially perpendicular to the head substrate 23, and has one end at an engaging hole (described later) of the head substrate 23 and the other. The stages are respectively engaged with one portion of the up-and-down movement 14 'of the instructor push button 14, and the central portion is provided with an integrally formed main shaft 33' at a predetermined position on the face of the chassis 20. It is hold | maintained by the pair of granular piece 34 formed. That is, as apparent from the description of FIGS. 1 and 2, the switching of the track to the recording stage 2 of the magnetic card 1 is performed by pressing the push buttons 13 and 14. In addition, 13 'and 15' indicate the shanghai-dong lever together with each of the push buttons 13 and 15, and 35 and 36 of the dashed lines show the interlocking links, and Since the associating operation of the push buttons 13, 14 and 15 through the link is as described above, redundant description is omitted.

Next, the operation apparatus of the card driving system and the circuit system in the present embodiment will be described.

In this type of card type recorder, the magnetic card 1 is made of a relatively tough material, and at the time when the card is inserted into the conveying passage, the power switch is turned on by the front side of the card itself and the card is turned on. Systems such as detecting a point in time at which a passage passes through the transfer passage, i.e., turning off the power by detecting the position of the end of recording or playback, belong to the disclosure. However, as a problem recognized in the conventional apparatus, particularly in the case of the recorder for recording and reproducing, the setting of the detection time of the front and back sides of the card, in other words, the configuration of the switching device on the card passage is unreasonable. Specifically, if the power supply is not turned on before the front edge of the magnetic card reaches the erase head, the first part of the recorder will not be erased, and if you try to avoid it, the track of any length of the rear part of the recorder will not be recorded. do. Needless to say, this is because the erasing head and the recording and playback head are usually arranged at a predetermined interval.

Therefore, the solution of this problem is to provide the respective switching devices in the near front position of the erasing head, the recording front, and the near front position of the playback head (so-called upstream side of the card passage). However, this is one of the causes of the increase in the price of this kind of recorder, so it is difficult to admit that it is an appropriate measure.

In the card type recorder of this example, a simple and reasonable configuration is taken to improve the above problems. In Fig. 3, reference numeral 37 denotes a microswitch for driving and an amplifier, 37 'denotes an operator thereof, and 38 denotes a movable member of a rotating material installed in association with the operator. By turning 38 in the direction of the arrow, the microswitch 37 is turned on. In the illustrated state, the movable element 38 is knitted in the counterclockwise direction by the elastic restoring force of the operator 37 '. Numeral 39 indicates the extraction of the mover. Exemplary reference numeral 38 is formed from a molded article of synthetic resin and has a shape as shown in FIG. That is, in the drawing, a pivot hole 39 'is formed in the rear base of the arm 40, which is bent in the front axis, and the first detection portion 41 is in the wider portion of the left portion, and the width of the widening portion is widened. The second detection section 42 is provided at each of the narrow stepped ends extending from the respective ends. Each of these first and second detectors 41 and 42 has a multi-angled planar shape and is a granular piece having a certain height from the plane of the arm 40. It is intended to contact the back of the magnetic card.

Then, at a predetermined interval from the first detection unit 41 and the second detection unit 42, the first detection unit 41 as shown in FIG. The detection part 42 of 2 is located in the near front position of the recording and reproducing head 26, respectively, and is located on the recess 22 of the guide tank 21, respectively. In other words, the first and second detectors 41 and 42 are located on both sides of the erase head 25.

Now, the magnetic card 1 is inserted into the groove 22 of the guide jaw 21 in the case in the card transfer groove 7 as shown and described in FIG. When sliding in the direction of '), the front side of the magnetic card touches the inclined surface of the first detection unit 41 and pushes it back. Thus, the entirety of the mover 38 is rotated clockwise as indicated by the arrow and turns on the microswitch 37 via the operator 37 '.

In this way, the composition system and the circuit system are in an on state, and the magnetic card 1 is transported at constant speed, and the recording on the first track 2a or the second track 2b of the recording stage 2, or which one. You can play from tracks. Of course, the erase current is not supplied at the time of regeneration.

In a short time, the front side of the magnetic card pushes the second detector 42 as described above, and for a while, the back surface of the magnetic card of the first and second detectors 41 and 42 is in contact with each other. The state of the furnace operation (recording or reproducing) is held, and finally, the rear side of the magnetic card passes through the second detection unit 42, the mover 38 is restored, and the microswitch 37 is also turned off. As described above, in the present example, the conventional problem can be solved by adopting a simple and clever configuration in which the first and second detection units are provided in a single mover. Particularly, during recording, the rear end of the magnetic track can be improved. It is a notable effect until it is completely erased.

FIG. 6 is a perspective view for explaining the head substrate 23, as opposed to that shown in FIG. The head board 23 of this example is formed of a sheet metal part having an approximately L-shaped substrate, and the above-described erasing head 25 and the recording and reproducing head 26 are disposed on the right side of the horizontal plate 43. The heavy-duty head 25 is mounted on the stepped side of the lever 45 which is squeezed to a part of the horizontal plate 43 so that the lever 45 can be clocked by, for example, a spring 46 wound around its spindle. Knitting in the direction. However, this structure is not directly related to the present invention, and this structure is an apparatus for properly setting the connection pressure of the erasing head 25 to the above-described writing table 2 (see FIG. 1). In addition, the right end 43a of the horizontal plate 43 on which the recording / reproducing head 26 is directly mounted is slightly higher, so that the level of the erasing head 25 and the recording / reproducing head 26 is constant. This is also a design issue. Further, the left part of the horizontal plate 43 is a thin plate 43b. 44 is a vertical plate. In the card type recorder of the present invention, for example, the head board 23 as shown in the drawing is fitted around the support shaft 24 (FIG. 3), the elastic knitting machine is turned clockwise, and it is displaced by a predetermined pitch in the vertical direction. This allows the erase head 25 and the recording / playback head 26 to correspond to any one of the first and second tracks 2a and 2b of the recording table 2 formed on the magnetic card 1. It is evident from the above that it is a mechanical two-track mononal type. It is also easy to understand that the important point in this mechanical switching method is in the correct positioning of the magnetic head relative to the writing table and the track and its holding means.

In this invention, in order to achieve the objective described in the above, it has the following structures as an example.

That is, in FIG. 6, reference numeral 47 denotes an upper plate formed by bending forward from the upper side of the head substrate 23, that is, a part of the vertical plate 44, and corresponding portions of the upper plate 47 and the horizontal plate 43. silver Represents the shape Holes 48: 48a and 48b are formed in the male part in common with the axes. That is, the above-described support shaft 24 is inserted into the holes 48. In addition, a hole 49 is also attached to the center of the vertical plate 44 on an axis line orthogonal to the axis of the hole 48, and a metal hole 50 is inserted into the hole 49, for example. At the same time (see FIG. 3), the outer exposed surface is pressed by the plate spring 51 so that the head board 23 moves up and down along the main surface of the support shaft 24 so as to creek. Positioning on the track is performed. Further, in FIGS. 3 and 6, reference numeral 52 denotes a snap ring attached to an upper end of the support shaft 24, and 53 denotes a right side of the vertical plate 44 of the head substrate 23 (FIG. 6 shows a left portion). Is a screw for adjusting the amount of knitting, and (54) is a support piece of the screw, and (55) denotes an engagement hole in which one end of the seesaw-lever (33) is inserted. 7A and 7B are enlarged views of portions cut along the line BB in FIG. 3, in which two forms at the time of track switching are shown, and corresponding parts of FIGS. 3 and 6 are denoted by the same reference numerals.

In the present invention, the lower portion of the support shaft 24 inserted into the hole 48 of the head substrate 23 is composed of, for example, a shaft portion 56 having a stage, and the shaft portion 56 and the upper end portion thereof. Dimension between the snap ring 52 and the head substrate 23 The difference from the thickness dimension of the male portion corresponds to the track pitch, and the first track 2a of the writing table 2 is also used when the head substrate 23 is in the upper limit position as shown in Fig. 7a and Fig. 7b. The case where the switch is to be switched to the lower limit position indicated in Fig. 2 is set so as to correspond to the second track 2b (see Fig. 1), and the switching operation is performed by the creek-type operation. Position it correctly so that it can be held in a stable state.

As the means, as shown in the drawing, the flanger 57 is formed in the middle of the support shaft 24 by cutting, for example, and the upper and lower surfaces thereof are inclined surfaces 57 'that are close to the conical shape, and the head substrate 23 is formed. The above-described operation is made possible by the interaction of the hole 49 of the vertical plate 44 of the vertical plate 44, the metal hole 50, the plate spring 51, and the flanger 57. Further, in the example, the diameter of the flanger 57 is the same as that of the upper and lower sliding portions, and the portion adjacent to the flanger 57 is bent to a small diameter as shown.

Next, the switching operation of the head substrate 23 will be described with reference to FIGS. 7 and 8. First, as shown in FIG. 7B, the head substrate 23 positioned on the side of the second track 2b is shown. In the hole 49 and under the pressure of the plate spring 51 on the outside, the metal ball 50 moves against the pressure of the plate spring 51 to cross the flanger 57. It protrudes outward and elastically recovers when the spherical surface faces the upper surface side of the flanger 57.

That is, this action is the creek operation at the time of switching, and the upper plate 47 of the head board 23 instantaneously abuts on the lower surface of the snap ring 52, so that the head board 23 also becomes the upper limit position.

However, pressing force in the horizontal arrow a direction by the plate spring 51 is applied to the metal ball-50 continuously (Fig. 8), and this pressure is changed by the upper inclined surface 57 'of the flanger. As a result, the inner circumferential upper portion of the hole 49 is pressed. Therefore, the head board 23 receives the upward pressure of arrow b on the vertical plate 44 and stably holds the upper limit position. The above operation is also the same when the head substrate 23 is switched from the first track to the second track side. Further, the diameters of the holes 49 and the metal holes 50 and the dimensions of the related members are selected as necessary. In this way, according to the present invention, in this type of card type recorder, the track switching corresponding to the recording table of the magnetic card can be performed easily and accurately, and there is little fear of causing an unevenness of the head position. All the irrationalities due to other track switching can be avoided, and the effect that is practical in combination with the simple configuration is very great.

In addition, in the above-described embodiment, the case where the snip ring 52 and the end diameter portion 56 are provided on the support shaft 24 as the surface position coupling means of the head substrate 23 has been described. As an example, it is also easy to arrange the contact member on the head substrate in the vicinity of the support shaft 24. In addition, the metal ball 50, the plate spring 51, and the like provided on the side of the head substrate 23 are not necessarily requirements of the present invention, but also use the appropriate elastic pressing member instead of the intended action and effect. Of course, the present invention can take various embodiments within the scope of the gist of the present invention.
