PURPOSE:To make a uniform tape running possible without the influence of the variance of the capacity of a cassette by providing a tape guide, which is provided with a tape running height regulating part and front and rear position regulating parts, on a head substrate. CONSTITUTION:Between tape guide pins 30 and 31, a tape 22 running in the direction of an arrow has the running height regulated with regulating parts 23- 26 and has running front and rear positions regulated with regulating parts 27 and 28 by tape guides 20 and 21 which are entered into a cassette aperture part from the external together with a head 11. Consequently, even if the degree of verticaity of tape guide pins 30 and 31 in the cassette is somewhat varied, the tape is always run uniformly without the influence of this variance. Since tape guides 20 and 21 are fixed together with bosses 14 and 16, special fixing means for fixing tape guides 20 and 21 are not necessary. Further, this device can be constituted in a narrow space without changing fundamentally conventional head constitution and head attaching structure. |
