6 Claims.
This invention relates to sound recording and reproducing apparatus, and more particularly to a dictating machine employing flat diskrecords for recording and transcribing sound.
when using the dictating unit of dictating machines wherein fiat disk records are used, it has hitherto been difilcult to mark the record to indicate the beginning and end of the dictation or the points where corrections are necessary. One form of a marker adapted for the above purpose was disclosed in my copending application, Serial No. 248,690, flied December 31, 1938, in which the indicating marks are superimposed by means of a crayon upon the sound grooves of the record. Thepresent invention contemplates the provision of means to apply indicating marks upon the central section of the record not designed to receive sound grooves, whereby the starting and ending of the dictation, and also the points at which corrections are made, may be readily located and permitting the record to be played back at such points to familiarize the user with the same before the entire letter is transcribed.
One object of this invention is to provide means carried by the recording arm of the dictating mechanism, which may be manually depressed to mark the central area of the flat disk record.
A further object is to provide a pointer movable with the pick-up arm of the transcribing unit of a dictating mechanism whereby the correction point may be quickly indicated and thus facilitating thedisposal of the pick-up needle in the proper sound groove.
will appear as the description proceeds, there has been illustrated in the accompanying drawing, one form in which the invention may be conveniently embodied in practice.
In the drawing: Fig. 1 is a perspective view of a dictating unit of a dictating machine having the improved correctlon marker installed thereon.
Fig. 2 is a top plan view of the turntable, disk record, recording arm, and the improved correction marker.
Fig. 3 is a side view of the same, looking in the direction of the arrow 3 of Fig. 2.
Fig. 4 is a top plan view of the turntable, disk record, pick-up 'arm and the indicating of the transcribing unit.
Fig. 5 is a side view of the same, looking in the direction of the arrow 5 in Fig. 4.
Referring now to ,the drawing wherein like reference numerals designate like parts throughout the several views, the numeral l0 denotes the casing of a dictating unit of the type shown and described in the above-mentioned copending application. This unit also includes a a rotatable turntable ll carrying a flat disk record l2, a dietating microphone IS, a swingable recording armll carrying a groove-cutting head l5, and suitable control knobs l6 and I1. A play-back unit is also shown associated with the dictating unit on the casing Ill, and comprises a swingable reproducer arm l8 carrying a pick-up head l9 and a loud speaker 20. The play-back unit is particularly adapted for the use of the person dictating, but may, if desired, be used for transcribing by a typist or other person. Preferably. .however, a separate transcribing unit, such as is shown in Figs. 4 andfi will be employed and located at a point remote from the dictating unit. This separate transcribing unit comprises a rotatable turntable 2|, a swingable reproducer arm 22, and a pick-up head 23.
In order to indent or scratch the central section 25 of the record l2 to produce marks 24 to indicate correction points, etc., provision is made of an arm 26 of thin spring strip material which is secured at one end by rivets 21 to the recording arm I, said arm 26 being directed at such an angle from said arm It as to cause its outer end 28 to overlie the blank central section 25 of the record i2. A hollow vertical lug 29 having a manipulating knob 30 at its upper end is secured to the free end 28 of the marking arm 26, and said lug 29 is adapted to receive a record-marking pointer needle 3| which may be'clamped in said lug by a thumb screw 32, whereby said needle may be vertically adjusted with respect to'the recordv l2. Preferably the record-marking needle 3| will be so adjusted that its lower end will be slightly above the upper surface of the record l2 when the cutting stylus 33 of the recording head I i is in operative contact with the record for cutting sound grooves 34 therein.
Operation In operation, the person dictating will talk into the microphone l3 to cause the groove-cutting stylus 33 to form sound grooves N on the outer portion of the record |2. If a correction is required, he will press down upon the manipulatgage the blank section 25 of the record l2, and thus producing a short arcuate mark 24'thereon (see Figs. 2 and 4) The same operation may be performed to indicate the beginning or end of ,a. letter. v During the play-back of the record for transcribing or other purposes, the typist will be enabled to accurately dispose the needle 35 of the pick-up head IQ of the play-back unit, or the needle 36 of the pick-up head 23 of the transcribing unit in the, proper sound groove 34 by means of a pointer arm 31. The latter arm 31 is formed of thin sheet metal, and is secured at its inner end to the arm 48 or the arm 22, as the case may be, by rivets 38. The pointer arm 31 extends at such an. angle to the respective play-back arm L8 or transcribing arm as to overlie the blank portion ing knob 30 to cause the marking needle 3| to enwill be manually depressed into contact with said central section. to form an indented groove thereon to indicate the particular groove of the outer portion of said disk to which attention is to be called.
3. In a dictating machine for operating on disk records, a dictating unit including a, record- 25 of the record i2,'and is preferably bent downwardly so that its pointed extremity will lie close to the surface of the record i2 without touching it. By means of this construction, when the extremity 39 of the pointer.3l lies adjacent one of 'the marks 24, the play-back needle 35, or the transcribing needle 36, respectively, will be accuratelyposition'ed over the proper sound groove at the point on the record corresponding to said .marks as above described.
One advantage of the present invention is that a permanent record may be made on the disk record itself of all corrections, beginnings and ends of letters, etc., and there will be no possibility of confusion or mix-ups as was formerly the case where correction-indicating markings were made on cards or other devices which were separate from the record.
While there has been disclosed in this specification one form in which the invention may be embodied, it is to be understood that this form is shown for the purpose of illustration only, and that the invention is not to be limited to the specific disclosure, but may be modified and embodied in various other forms without departing from its spirit. In short, the inventionincludes all the modifications and embodiments coming withinthe scope of the following claims.
